ANTISKID DEVICE.

To all w/wn/t may concern.

Be it known that I` THOMAS H. BELL, a citizen of the United States, residingr at New York city, in the county of New York and State of New York, have invented eerand useful lmproven'ients in Antithe following is a tain new skid Devices, of which specification.

This invention. has relation to limeulnatio tires or casings. and has for an object to includes a metallic plate formed to closely engage and conform to the surface ot a tire easing, means for securing the wheel, and urtieulated or linked elements rh'et'erably Secured to the securin,f 1r means for the pluto and extending over the plate to atlord Asutlicienl t'rif'tionzil engagement with the ground or road to prevent skidding, to enable the vehicle to extricate itself from slippery places as well as other purposes and advantages which will appear as the nature of the invention is more specifically `set forth.

Another object of the invention is to provide a device havingr the eharaoteristiaxs above set forth and inoludug specifically n steel plate tu extend trmruersely across the tread of a, tire casing with n removable means applied to each end thereof adapted to be eonnemed through the medium of :i .strap or other flexible element. and one or more Seotions` olf chains having their end links con nected to sind seruriinr means whereby to relieve strain upon the plate and to provide securing inea-ns as will presently appear.

In addition to the forrlfoinu'. thisiuven-- tion eouiprelwnds iu l'n'ovements in the details ot' construction and arrangement of parte', to beI hereinafter described and pary ticularly set forth in the appended claim.

In the ncconlpanviinr drawings in Whigh similar and eorresluinding parts are designated by the same characters of reference throughout the Lseveral views in u'hir-h they appear-- Figure 1 is a view in side elevation of a vehiele wheel illustrating the application thereto of a plurelity of devices constructed vin acoordanoe with my invention.

Fig'. 2 is a View of one of the devices in section, and

Fig. 3 is a View' partly in section.

Cates a plate formed `preferably of steel although it will be obvious that any other suitable material muy be utilized. Said plate is curved transveisely und longitudi nlly to .engage and closely tit the tread 11 ot a tire casingr indicated at 12. It will be noted that the ends of the plate 10 extend to a point adjacent the felly of the vehicle wheel. The plate is furthermore formed upon its longitudinal edges with a` turned over portion 13 formed by pressing,r or otlrerwise bendinLr the material forming the plete, said bend being;r directed outward so as to afford a rounded corner upon the edges of the plate to prevent the saule from inurring or injuring the surface ol the tire in the event that the armor plate should become tilted during use. The ends of the plate are provided with apertures 1-l, and at each end I provide a clip which is formed by bending a rod or heavy wire 15 into substantially 'U-shaped configuration with'thev terminals thereof rounded to form hooked portions 16 which enter the openings 14. To prevent aoeidental dislodgment of the securingr elements from the plate I provide e steel spring 17 secured by means of a rivet or the like 18 to the intermediate portion of a. connecting member l5 with the opposite end of the spring finger engaged Within the inner surface of the turned over or hooked port-ion 16 as clearly shown in Fig. il. I next provide :t connecting element in the form of a strap. .To one of the clips l attach a strap 19 of leather or other suitable materiel bent around'the bight portion of the clip and the end secured-to the strep `by means of rivets 20. Upon the other clip I mount a buckle 21 of conventional type through the medium of a. link 22 of leather to prolide flexibility. Extending' longitudinallvof the plate 10 and upon the outer surface is a pair of sections of chains 23 or other suitable articulated elements with the end links engagedwupon the hook terminals 1li of the clips as shown in Fig. '2. I also provide a lining 24 of canvas or other Suitable material upon the inner [surface of the plate 10.

In use.` one or more of these devices are employed and it will be seen fromFig. 1 that the plates are embraced about the pneumatic tire tQ extend transversely thereof, the Strap 19 being* brought beneath the felly and inserted in the buckle 21 thereby securelv reids edges 13 will prevent taining the device against movement. will be obvious that owinp,r to the provision of one or more of these devices skidding will be prevented because of the firm fric' tional engagement provided between the tire und surfuceof the rond. Also, this device will be of pnrticulnrvulue in extrivnting n v ehicle fuoni soft ground because of the excellent tractive quitlities imparted to the tire by the provision of these devices. In the event that the device should become tilted during use it is apparent that the rounded the tread surface of the tire from becoming marred or otherwise injured. It will also'be obvious because of the connection of the flexible elements 23 directly with the clip 15, iell strain upon the plate 1U will be obvinted. Other useful axlvantages will readily occur to those familier with the art to which this invention appertains.

While I have illustrated and described my invention with some degree of perticulerity,

I realize that in practice various alterations therein may be m de. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended 80 claim.

Having thus described my inventiomwhat I clnim as new und desire to secure by UnitedStates Letters Patent is:

An enti-skid device comprising a metallic plate adapted to extend transversely of 'a pneumatic tire und conforming to the transversie curvature of the latter, each end of said plate having e pair of closely spaced openings, a. pair of chains resting upon the plate each of e length to permit the opening of each end link to register with one of the said openings of the plete, a pair'of U shaped wire clips each having their terminals curved. and seid terminals entered through the openings of the plate and through the registering;r end links, nud moans to connect the hight portion of one clip with the bight portion of the other clip.

l In testimony whereof I nilix my signature 60 in presence of two witnesses.
